When I lived in Michigan I bought greensand at a bulk animal feed store that also carried organic gardening supplies. Greensand is very popular with people who grow hosta because it is wonderful for root development in tissue cultured hosta and promotes increase. It was a hosta person who recommended I try it on daylilies for rapid root development in the seedling stage. If you mail out daylilies, you have to watch that you don't overdo with it or your root systems will get too big for your boxes and it will cost you a fortune in postage! But I like that it is a long lasting organic product. It lasts about 3 years in the soil.
I couldn't find greensand anywhere once I moved to North Carolina, but Ace is the place with the helpful hardware man (!) so I found an ACE Tru Value Hardware store that carries animal and gardening supplies and they special order it for me. What I get is an Espoma product that comes in a 35 pound bag so you should be able to get it from any place that carries Espoma products. The smaller 4 or 5 pound bags are really expensive and it saves a lot of money buying the large bag. Espoma makes very popular gardening products so you should be able to find where they sell their products. Here is a link to the Espoma website. You can do a search to find a dealer near you.
